SLOT AND SLUG FOR VENDING DEVICES.

To all whom it may concern:

Be it known that I, HENRY Gon'rz, citizen of the United States, residing at Chicago, in'the county of Cook and State of Illinois, have invented cjertain new and useful Im- Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- .tains to make and use the same. 1

This invention has for its object to pro-v videa device for useon telephone 'tollboxes and vending-machines whereby the insertion into the same of any except given shapes of slugs particularly adapted to'the box ordevice is prevented whereby fraudulent'insertion of counterfeit coins or metal disks is obviated. 1

g @The invention consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanyingdrawings illustrating the invention: Figure -1 is a fragmentary detail-vertical section through the coin chute portion of a telephone toll-box or other vending machine equipped with devices embodying my invention. Fig. -2-

is a fragmentary view in front elevation of the front wall of a telephone toll-box or the like showing the opening for receiving the coins or slugs equipped with devices embodying my invention. Fig. --3' is a fragmentary rear elevation of the rear wall of the coin slot showing the means for securing thereto the devices embodying my invention. Fig. f1 comprises an end view and a frontview respectively, of the slug adapted to be used in connection with the devices disposedin the coin or slug receiving opening of the toll-box or other de- Fig. is a fragmentary detail vices. horizontal section on the line 55 of Fig. 2-. Fig. -6- is a view similar to Fig. .1 showing a modified form of construe tion. i i j i v Mydevice has forits object to provide a coin receiving opening for the coin-chute of a telephone toll-box or other vending machine and a disk or slug therefor provided with coacting means whereby only the intended disk or slug may be inserted and fraudulent insertion'of disks and counterfeit coins prevented. g j i In the front wall 1 of the housing of a telephone toll-box or other vending machine,

Application filed July 1, 1912. Serial No. 707,100.

I provide a circular opening 2. Extending parallel withthe wall 1 at adistance therefrom substantially equal to the thickness of a coin of the desired denomination adapted for use in the box or device is a wall 3 between which and the wall 1 the coin or slug is adaptedto be guided as it drops by gravity into engagement with any suitably coinoperated or coin-controlled means provided in the device. The front wall 1 is provided with a semi-cylindrical flange 4 bordering the opening 2 and extending to the rear wall 3. Secured to said plate or wall 3 and projecting into and through said opening 2 is a -member 8 which, in the instance illustrated, consists of a flat plate having projections'9 which are passed through slots or openings 10 in the plateor wall 3 and are flattened out in the manner of rivets to firmly secure said member 8 in place. The said plate or member 8 is preferably vertically disposed in theplane of the vertical diameter of the opening 2and is of greater width at its upper end than the depth of the wall and its flange 4, the outer or proje'cting end portion thereof terminating in a projection 11 extending upwardly along thefront wall 1. The outer vertical edge of said projection 11 and the contiguous portion of the plate 8 is preferably beveled, as

at 12. At its lower end the said plate 8 is provided with a projection or. ward 13 which maybe circular, as shown, or of any other convenient shape but which projects beyond at least oneside face of said plate or member 8. The width of the plate or member 8 between the rear face of the projection or ward 13 andthe opposing face ofthe plate or wall 3 is preferably substantially equal to thethickness of the slug 14 adapted to beused, it being essentiahof course, that the latter befreely' movable between said plate or wall 3 and the opposing face or faces of said projection or ward 13. The

said plateor member 8 is cut away, as at 15, from the point contiguous to the upper end of the projection or ward 1.3 and to a point in vertical alinement' with the front edge of the projection 11, said recess or cut-away portion 15 being of such depth as to render the plate or member 8 of less width immediately above the said projection 13 than the thickness of the slug 14. The said slug 1a is circular and corresponds substantially in diameter with the diameter of the opening 2.

It will be understood, of course, that the opening 2 may be of any other shape desired than cylindrical and that the slug 14 may be of a shape and size corresponding to that of the opening 2 so that it may bereadily inserted within the latter. As a circular slug is most convenient I have illustrated this shape and a corresponding shape of opening 2 in the drawings. The slug is provided with a recess or slot 16 therethrough extending from an edge thereof radially inwardly to any desired depth corresponding withthe distance of the upper end of the projection or ward 13 from the point in the wall of the opening 2 in vertical alinem ent therewith. At least one wall of saidrecess or slot 16 is provided with a notch corresponding in shape and size with the projection or ward 13 which is adapted to be received therein. In the instance illustrated the slot 16 terminates at its inner end in acircular opening or notch 17 of greater diameter than the width of the slot but this particular arrangement may be changed and varied without departing from the invention. To insert a slug 1 1 into the said opening 2 the same is positioned so that the slot or recess 16 therein i s-vertically disposed and its mouth uppermost and is first placed to receive the'projection 11 which is beveled to render insertion easy and is then moved downwardly until it is flush with the opening 2 adapted to receive the same whereupon it may be longitudinally moved into said opening. In this position the opening or notch 17 will register with the projection or ward 18 and in moving thesaid slug 14 toward. the plate or wall 3 said projection or ward 13 will pass through said opening or notch 17. Owingto the depth of the cutaway portion or recess 15 in the plate or member 8 the slug may be moved rearwardly until it comes in contact with the plate or wall 3 and by then releasing the same it will drop by gravity, and in a direction laterally of its direction of insertion, between said walls, 1 and 3.

The device is very simpleand efficient enabling the slug to be easily manipulated for insertioninto the toll-box or other device for receiving the same. i I

'The particular means, herein illustrated and described are capable of being variously modified in substantially the same manner as are locks and keys therefor. Inthe accompanying drawings I have illustrated only one specific form of slug and means in the slot adapted to, the use of said slug but do not wishto be, limited to this specifie form as my invention comprehends many modifications thereof falling within the scope of the appended claims.

In Fig. .6 Ihave shgwna, modified form. of construction in which a sleeye- 18 is S e -"e to th er WEB-.01? he hute and erpi sts hreush h creates. he on wall thereof, said sleeve being cut away through an arc of about one-hundred-eighty degrees to permit a slug or disk inserted and having an opening in its front wall for the admission of a slug,tof a slug adapted to slide within said chute, thesaid slug. be ing slotted transversely of its faces; and a slug selector comprising guides mounted within the said opening and adapted toco act with the slots in said slug, oneof the said guides extending forwardly from the rear wall of the chute and adapted to guide the slug into registration with the bore ofi the chute, the other of said guides being adapted to hold the slug substantially in transverse alinement with the said opening until-the slug registers with the bore of the chute. v 2. The combination with a' chute having substantially parallel front andrearwalls and having an opening in its front wall for.

the admission of a slug, Ofa slug adapted to slide within said chute, the 'said slug being slotted transversely of itsfaces; and having the slug selector comprising guides mounted within the said opening and adapted to coact wit-lithe slots in the saidslug, one of the said guides extending forwardly. from the rear wall of the-chute and adapted to guide the slug into registration with the bore of the chute, the other of said guides being adapted to hold the slug substantially in transverse alinement with the said opening until the slug registers with the bore of the chute; the formerof said guides being cut away to permit the entrance of a finger for digitally pressing theginserted slug into proper'position for aliningwith the said hereof the chute. I

-3. The combination with a chute having substantially parallel front and. rear walls and having an opening in the front rwall thereof for admitting a slug'in adirection transverse to the face of the slug, of a pair of slug-selecting guides mounted within the said opening transversely; of the front wall of the chute, one of, the said guidesextend- 'ing substantially to the rear wall of the chute, the other of said guides terminating substantially flush with thejforward edge'of the bore. of'thechute; and a, slug having a pairof slots transversely of its face adapt; ed to coact respectively with the said guides, wherebyboth of said guides will holdthe slug-.- subeieellie y-r ransverse. ahaement with the said opening when the slug is digitally inserted until the slug registers with the bore of, the chute, and whereby the *latter of said guides will release thefslug for admission by gravity-into the bore of the chute when the slug has reached the said registering position.

ward of less length than said rib, of a disk corresponding in shape and size with said opening and adapted to be inserted therein,

there being a slotvthrough said disk extend- Oopies of this patent may be obtained for ing inwardly from an edge thereof and laterally enlarged at its inner end for permitting said rib and its ward to pass therethrough in the direction of the longitudinal axis of said slug as the latter is inserted through said opening, said ward terminating in the plane of the inner face of the wall of the chute provided with said opening, whereby when said disk has passed through the latter it will drop by gravity edgewise into said chute.

In'testimony whereof I have signed my name in presence of two subscribing witnesses.
